CLUTCH-m1 M' GIiAi I M- TofaZZ whom it mag concern;

Be it known that I, WILLIAM H. KArrEs,a citizen of the United States of America, and resident of Cincinnati, in the county of Hamilton and State; of Ohio,-have invented a new anduse-ful Improvement in'a Clutch- Trip.Mechanism, of which thefollowing is a specification;

My invention relates to, tripfmechanisms of the type in which, theoperator must operate two hand levers jointly to trip the mechanism, thereby eliminating any possibilityof the operator having one of his hands dangerously exposed/ ,An object of my invention is to eliminate several of the parts of uch, mechanisms heretofore used, thereby making the'devicel safer, simpler. and more efficient,

Another object is to eliminate possible sticking and jamming o'fr -the' mechanism These and otherv objects "areattained by the means described herein and disclosed the accompanying drawing in which:

Figurel is a fragmental-side elevation of a-punch press to whichmy invention has been applied. I

Fig. 2 is an enlarged elevation of the trip mechanism forming a detail of my invention.

Fig. 3 is a sectional view on line 3-3 of Fig. 2. V

My invention comprises a housing A supporting the pull bars B adapted to actuate trip bar C when both pull bars are jointly actuated.

The housing A has formed in it a central way a in which the trip bar C is adapted to be reciprocated. I A second way a formed in the housing is adapted to accommodate the pull bars I) and b, and has projecting into it the lugs a and a A cover a, is mountedupon the housing andincloses the pull bars and trip bar betweenitself and the housing. The perforated lugs a are formed on the side of the housing and serve as a means of attachment of the housing to the machine D.

The pull bars 6 and b are constructed similar to one another and comprise a perforated shank 6 a shoulder 6 the arm 6 and finger N. A slot 6 extends partly through the shoulder and the arm. The pull bars are adapted to slidably engage the bottom a of the way a and the top 0 of the trip I a pn atioa'medaag st 5',

bar C. The pull bar. is so placed in the way a"th at the lug a may abut the" shoulder 63 andthe fingers 6 The side b of the shoulder opposite to that portion that may engagethe lug a is inclined and'extends upwardly toward the arm 1)? terminating immediately adj a'cent to avsimilar inclined'surr face If "formed'on the adjacent pull bar, both inclined surfaces having a common pointllof conver ence'. i I

The trip bar C comprises a shank 0 adapted'to be reciprocated in the way a andhas projected upward therefrom and extending into the way a the lug c adapted to as: sulne a position immediately below the inclined surfaces b formed 'on the pull bars. I A ba'll'E is adapted to rest upon the lug ciand to engage the vinclinedsurfaces 7) upon the pullbars and to transmit the joint reciprocation of the pull bars to the trip bar. ,The slot 12 in the pull bars is so placed that the pull barsmay be moved toward. the.

lug'c' andiwill permit said lug'to enter said slots.

The'operation of 'my device'is as follows;

The hand levers F and F mounted upon the machine D are attached to thepull bars I) and b by the rods f and f respectively. When both levers F and F are actuated the pull bars are moved upon the ball E.

forcing the ball and the lug 0 in the line of motion of the pull bars thereby moving the trip bar C downward. The trip bar is at its upper end 0 attached to a clutch, not shown, upon the machine D, the said clutch being moved to a power transmitting position when the trip bar C'is moved downward. When the pressure on the levers F and F is withdrawn, the spring mounted on the clutch and whichnormally withholds the driving from the driven clutch member, returns the parts to their normal positions.

If one of the levers, for example F,'is moved downward, the pull bar b is likewise moved downward; such downward movement of the pull bar I) pushes the ball upon it, I have provided a means for operating the trip bar by foot, which consists in a link 9. 'movably connected to the trip bar C by being inserted in the hole therein, and connected referably by means of a chain G with a oot lever not shown. When the foot control mechanism is out of commission the link .g is unhooked from the trip bar and hung on the pulley spindle 9'.

What I claim is Y 1. In a clutch trip device the combination with a trip bar, of means adapted to be separately reciprocated and a ball adapted to transmit the joint movement of the reciprocating means to the trip bar.

2. In a clutch trip mechanism the combination with a trip bar, pull bars adapted to be reciprocated in parallelism, each bar comprising a shank, a shoulder, and an arm, the adjoining surfaces of the arms being'immediatelyadjacent, aball, and means mounted on the trip bar adapted to support the ball between itself, the shoulders and the shanks of the pull bars.

3. In a clutch trip mechanism the combination witha trip bar, of alug on the trip bar, reciprocatory pull bars mounted adjacent to the trip bar, and a ball adapted to transmit the joint reciprocation of the pull bars to. the lug.

4. In a clutch trip mechanism the combination with a housing having two ways, of a trip bar adapted to be reciprocated in one of the ways, a lug on the trip bar extending into the second way, pull bars reciprocated within the second way, theslots in the pull bars being in reciprocating alinement with the lug, and a ball interposed between the slotted portions ofthe pull bars and the lug, said ball being adapted to permit individual movement of any pull bar and to transmit the joint reciprocation of the pull bars to the lug.

6. In a clutch trip mechanism the combination with a housing having two ways therein, of a trip bar adapted to be reciprocated in one of the ways, a lug mounted on the trip bar and projecting into the second way, pull bars mounted'in the secondway and adapted to be reciprocated within the second'way, a ball interposed between the lug and the pull bars and adapted to transmit the joint reciprocation of the pull bars to thelug, and a cover adapted to extend over the'second way. a

In witness whereof, I have hereunto subscribe my name this 3rd day of August,

WILLIAM H, KAPPES;
